W'ILLIAM BUTLER SIMPSON, OF BENTON, LOUISIANA.

WAGON-SPRING.

SPECIFICATION forming part of Letters Patent No. 598,024, dated January25, 1898.

Application filed March 10, 1897.

To aZZ whom it may concern:

Be it known that 1, WILLIAM BUTLER SIMP- SON, a citizen of the UnitedStates, residing at Benton, in the parish of Bossier and State ofLouisiana, have invented a new and useful Spring Attachment forVV-agons, of which the following is a specification.

This invention relates to detachable and portable spring attachments forwagons,

adapted to be removably supported on the.

bolsters of the vehicle and to be detachably connected to the body ofthe vehicle, the object being to provide an attachment of this characterwhich may be interposed between the body and the running-gear of avehicle and removed therefrom as occasion may demand.

With this object in view the invention consists in the several detailsof construction and combination of parts hereinafter fully described,and particularly pointed out in the claims.

In the drawings, Figure 1 is a plan view of the running-gear of thewagon with my spring attachment in position. Fig. 2 is a side elevationof a wagon with my invention applied thereto, the wheels being shown indotted lines. Fig. 3 is alongitudinal section through the springattachment and the bottom of the wagon-body.

Similar reference-numerals indicate similar parts in the severalfigures.

The front and rear bolsters are designated 1 and 2, respectively, an d 3indicates the wagonbody. These parts may be of any ordinary constructionand form no part of the present invention.

The spring attachment consists of the sid bars 4, each being provided atits ends with hooks 5, adapted to fit over the front and rear bolstersof the wagon to hold the attachment firmly in position. v

6 represents crossbars connecting the two side bars 4: to prevent anylateral movement between them. These cross-bars are preferably arrangedat the rear end port-ions of the side bars, and on the cross-bars aresupported semi-elliptical leaf -springs 7. The ends of the springs 7 arebent to form hooks 8, which fit over the cross-bars and securely holdthe springs in position. On the upper surface of each of these springsis secured a plate 9,

Serial No. 626 ,867. (No model.)

which plates extend parallel with the side bars and are detachablyconnected to the bottom of the wagon-body 3 by bolts 10 or othersuitable fastening devices. To the front ends of the side bars at issecured another semielliptical leaf spring 11, extending transverselybetween them, and on the upper surface of this spring is secured a plate12, which extends transversely of the side bars and is adapted to bedetachably connected to the front end of the bottom of the wagon-body bybolts 13 or other suitable fastening devices. The ends of the spring 11are bent to form hooks 14, which fit over staples 15, firmly secured inthe side bars 4 and projecting from their lower faces.

When it is desired to use my attachment, the body of the wagon isdisconnected from the bolsters and lifted up sufficiently to enable thespring attachment to be placed below it and the hooks 5 to engage withthe front and rear bolsters, when the body may be lowered and secured tothe plates 9 and 12. In this manner a wagon that is ordinarily usedwithout springs for the purpose of hauling heavy loads may be convertedinto a spring-wagon which will be suitable for light loads or for theconveyance of passengers. It will be readily seen that the springattachment can be put in position or removed at pleasure and that itwill not necessitate any changes whatever in the body of the wagon orthe runninggear ordinarily employed; also, that it will occupy verylittle space when not in use and will be of such weight as to be easilyhandled.

These attachments may be made of varying sizes adapted to fit wagons ofdifferent sizes, and it is to be understood that changes in the form,proportion, and minor details of construction may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of thisinvention.

Having thus described my invention, what I claim is- 1. A portablespring attachment for wagons, consisting of two side bars having hooksat their ends to fit over the bolsters on the running-gear, staplessecured to the side bars near one end thereof, a semi-ellipticalleafspring extending transversely between the side bars and having hooksat its ends to enconnecting the rear end portions of the side bars,springssupported by said cross-bars and extending parallel to the sidebars, plates secured on the upper surfaces of the springs, and devicesto detachably connect the plates to the bottom of the Wagon-body,substantially as described.

In testimony that I claim. the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

WILLIAM BUTLER SIMPSON.
